Deuteronomy 29:11-14 -

The covenant was a national engagement, and as such included not only the adults anti existing generation, but the little ones, the strangers resident in Israel, the lowest menial servants, that is, all the elements of which the nation was composed, as well as their posterity in coming, generations. That thou shouldest enter into covenant. The expression in the Hebrew is a strong one, indicating not a mere formal engagement, but a going thoroughly into the covenant; the phrase is used of the sword going through the land (Le Deuteronomy 26:6 ), and of one going into the pit ( Job 33:28 ). Into his oath. Covenants were confirmed by oath ( Genesis 26:28 ; Hebrews 6:17 ); hence in Scripture the covenant of God is sometimes called his oath ( Deuteronomy 29:14 ; 1 Chronicles 16:16 ; Hebrews 7:28 ). (On Deuteronomy 29:13 , cf. Deuteronomy 28:9 ; Deuteronomy 27:9 ; Exodus 19:5 , Exodus 19:6 .)
